Title
(EN) SHOE CONSTRUCTION
(FR) CONFORMATION D'UNE CHAUSSURE
Abstract
(EN) A shoe (10) having an insole (12) with a forepart (14) of leather having the characteristics of upper leather and a back part (16) of fiberboard. A sheet layer of foam material (48), such as microcellular polyurethane, is cemented to the lower surface of the forepart and a foam cushion (58), preferably molded of microcellular polyurethane, overlies the back part. The back part of the insole has an opening (56) through it and the foam cushion has a central portion (62) that projects downwardly through the opening thereby providing a thickened foam at the central portion to maximize cushioning at the area of the heel strike. The invention is incorporated in shoes of both the welt-type construction and the cement-type construction.
(FR) L'invention se rapporte à une chaussure (10) possédant une première semelle (12) pourvue d'une partie avant (14) en cuir présentant les caractéristiques d'un cuir supérieur, et une partie arrière (16) en carton de fibre. Une couche de mousse (48), telle que du polyuréthane microcellulaire, recouvre la partie arrière. La partie arrière de la première semelle possède une ouverture (56) qui la traverse et le coussin de mousse comporte une partie centrale (62) qui se projette vers le bas et traverse l'ouverture, ce qui permet d'obtenir une mousse plus épaisse au niveau de la partie centrale afin de maximiser l'amortissement au niveau de la région de contact du talon. L'invention concerne également des chaussures à conformation de type trépointe ou de type collé.
